Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

problem #2

Trailblazer EXT LS V6

  • Automatic transmission
  • 118,500 miles


one day the car is fine and the next a dead battery, nothing is on, no light, not radio, no AC. something is draining power from the battery. one time I couldn't turn or remove the key, have to keep jumper cables in the car and back into a parking space just in case I need a jump. Replaced battery several times, replaced alternator and coils. Recall on the gas tank which was replaced. Just can't figure out what is draining the battery. I was at a stop sign and it stalled, stalled when pulling into a parking space at the grocery store. Started it and left right away, service engine light blinking and running very rough, this is when the coil was changed and it was fine for a few days then a dead battery. friend at work having same issue. Will ask mechanic to check fuses next.
